Description
The SA604A is an improved monolithic low-power FM IF system incorporating two limiting intermediate frequency amplifiers, quadrature detector, muting, logarithmic received signal strength indicator, and voltage regulator.
Features
- Low power consumption: 3.3 mA typical.
- Temperature compensated logarithmic Received Signal Strength Indicator (RSSI) with
a dynamic range in excess of 90 dB.
- Two audio outputs.
- muted and un-muted.
- Low external component count; suitable for crystal/ceramic filters.
- Excellent sensitivity: 1.5 V across input pins (0.22 V into 50 matching network) for
12 dB SINAD (Signal-to-Noise and Distortion ratio) at 455 kHz.
- SA604A meets cellular radio specifications.
